Sterba Cory

[janjan]

I have 3 sterba Cory's in a 50 gal tank...the male cory seems to be getting lighter in color than the other 2. I noticed this going on for about the last 6 mos. He still eats and swims a lot...the cory have been trying to mate.

Water is fine. I have had these fish about 9 years...Is this normal sign of aging???

ammonia 0
nitrates 0
nitrites 0
ph 7.4

20% water change weekly.

They share a tank with 12 neons, 6 silver tip tetra, 3 panda cory, and 6 gold dust mollies.

Not positive...but I'm pretty sure its normal If they're still eating just fine and not acting any differently, then I dont think I would be worried.

Sometimes discolorations can result from stress...but if his whole body color is changing...I dont think I'd worry.

They should be just fine if they are eating ok and still swimming around normally.
